It’s ‘game over’ for participants of the Great Canadian Appathon.

The race to make the best mobile gaming APP ended Sunday afternoon.

Teams of university and college students across Canada had 48 hours to develop a mobile game from scratch.

This year’s theme was retro.

Contestants were instructed to make a game with an ‘old school’ twist.

Students from Wilfrid Laurier University and University of Waterloo were in the running.

“We started on Friday so we slept on the floor in here because we’re from Cambridge so we couldn’t go anywhere,” says Vaughan Hilts, WLU Computer Science student. “So we slept right on the floor, just passed out, personally no blankets or anything for me.”

The top prize $25, 000 and a chance to have the game published by a leading gaming company.
